Security Tokens: How do they work?

The tsecurity checks They are a great solution in the world of cryptocurrencies, providing an additional layer of protection for users by acting as a physical or digital authentication device. In this blog, we'll read about the different types of security tokens and how they work.

Let's begin by defining what a security token is:

A security token is a physical or digital device that provides users with two-factor authentication (2FA) to verify your identity during the login process. They are most commonly used to access computer networks, but can also secure physical access to buildings and act as electronic signatures for documents.

How do they work?

These tokens provide authentication that allows access to any system through a device that generates a password, from a smart card to a key or a radio frequency identification card. The great thing about tokens is that you will always have a new password generated to log in to a computer or private network.

Security Tokens

Security token technology relies on a device that generates random numbers, encrypts them, and sends them to a server along with the user's authentication information. The server then sends an encrypted response that only the device can decrypt. The device is reused for each authentication, so the server doesn't have to store any usernames or passwords, making the system less vulnerable to hackers.

Today there are several types of security tokens; here we will mention and explain the main ones:

  • Connected Tokens: This is a physical object that connects to a computer; this device reads the connected token and grants or denies access.
  • Contactless cards: Establishing a logical connection to a computer without a physical connection is the purpose of contactless tokens. By connecting wirelessly to the system, these tokens can grant or deny access as needed. A prime example of this is Bluetooth, which is often used to create a contactless token connection.
  • Tokens Disconnected: The security token here doesn't need to connect to any type of device; what happens is that the device generates a OTP as a credential. Then an app sends a text message to the registered phone number, allowing users to log in. Both devices then link and grant access.
  • One-time login software tokens: Single Sign-On (SSO) software tokens act as digital librarians. They remember important information, such as a username or password, for people who use multiple computer systems and network services. This way, these people can log in to each system without having to remember multiple usernames and passwords.

  • Like all types of technology, tokens offer both advantages and disadvantages; here are some of them.

    Although passwords and user IDs have been around longer and remain the most widely used form of authentication, security tokens are a better option when it comes to protecting networks and digital systems. The downside of using passwords and user IDs is that hackers have refined their methods and tools, so they can sometimes crack them easily. Another way passwords can be compromised is through a data breach that exposes this type of information.

With all this information, we hope it's clear how security tokens work; remember that the The Cloud Group we develop mobile apps adaptable to Tokens or that give unique codes that can be merged with other applications, contact us to give you all the information you need.
